Tracie, if you plan to write further on this, may I suggest bringing rural areas into the discussion? It’s astonishing how much of farm country is a “food desert”, as explained here: http://blog.lib.umn.edu/draeg001/regionalpartnerships/2012/02/everyday-heroes-behind-the-sce.html

With various “get big or get out” pressures on rural America — towns that are “too small” risk losing their post offices just as farms that are “too small” can’t get USDA loans — it seems as if there’s a push favoring Big Ag just as we’re finding that Big Ag is hazardous to our long-term health.
